Electrochemical promotion of catalysis over Pd nanoparticles for CO2 reduction.
Electrochemical promotion of catalysis (EPOC) has been shown to accelerate the rate of many heterogeneous catalytic reactions; however, it has rarely been reported in low-temperature aqueous electrochemical reactions. Herein, we report a significant EPOC effect for the CO2 reduction to generate formate over Pd nanoparticles (NPs) in a 1 M KHCO3 aqueous solution. By applying a negative potential...
متن کاملElectrochemical promotion of propane oxidation on Pt deposited on a dense β″-Al2O3 ceramic Ag+ conductor
A new kind of electrochemical catalyst based on a Pt porous catalyst film deposited on a β″-Al2O3 ceramic Ag(+) conductor was developed and evaluated during propane oxidation. It was observed that, upon anodic polarization, the rate of propane combustion was significantly electropromoted up to 400%. Moreover, for the first time, exponential increase of the catalytic rate was evidenced during ga...
متن کاملRecent Developments of Electrochemical Promotion of Catalysis in the Techniques of DeNOx
Electrochemical promotion of catalysis reactions (EPOC) is one of the most significant discoveries in the field of catalytic and environmental protection. The work presented in this paper focuses on the aspects of reaction mechanism, influencing factors, and recent positive results. It has been shown with more than 80 different catalytic systems that the catalytic activity and selectivity of co...
متن کاملThe Promotion of Base Metal Catalysts for the Electrochemical Oxygen Evolution Reaction
ii Acknowledgements I would like to start by acknowledging those who have played an instrumental role in my achieving this level of academic success. This starts with my mom and dad; the two of them have always encouraged me to ask questions, be curious and helped to introduce concepts and ideas that have shaped me to this day. I have had many wonderful teachers and I am thankful to all of them...
متن کاملNon - Faradaic Electrochemical Modification of Catalytic Activity REVERSIBLE PROMOTION OF PLATINUM METALS CATALYSTS
The catalytic activity and selectivity of platinum metals can be altered dramatically and reversibly by interfacing the metal with a solid electrolyte which supplies ions onto the catalyst sugace under the influence of an external potential. The induced change in catalytic rate is orders of magnitude higher than the rate of ion supply. This new effect has revealed a surprisingly simple exponent...
